Rockfill dams are accounted as useful measures in watershed management projects. How-ever, the sediment transport through the rockfill materials, could impact their lifetime duration. Previously, researches have been conducted to describe the various hydraulically issues of the flow passing through these structures However; there is no general relationship to estimate the sediment transport rat...

purification quality of CLP is important, especially for analyses of T-cell development. The original phenotypic CLP has recently been refined by addition of positivity for Flk25 and now a smaller population of cells including CD27 are shown to contain the T-cell potential. A specific criticism of the CLP as the thymus-seeding cell has been the lack of evidence that CLP can be detected in thymu...

BACKGROUND Peak oxygen consumption (Vo(2)) is routinely assessed in patients with heart failure undergoing cardiopulmonary exercise testing. The purpose of the present investigation was to determine the prognostic ability of several established peak Vo(2) prediction equations in a large heart failure cohort. METHODS AND RESULTS One thousand one hundred sixty-five subjects (70% males; age, 57....

Evidence from a number of sources now suggests that the visuo-spatial sketchpad (VSSP) of working memory may be composed of two subsystems: one for maintaining visual information and the other for spatial information. In this paper we present three experiments that examine this fractionation using a developmental approach. In Experiment 1, 5-, 8-, and 10-year old children were presented with a ...

The 10(th) December 2010 marked a new beginning for Regulation (EC) no. 1272/2008 on the classification, labelling and packaging of substances and mixtures (CLP) in Ireland with the start of its operational phase. It was on this date that the administrative and enforcement provisions for CLP were encompassed in the new Chemicals Amendment Act, 2010. In this Act, the Health and Safety Authority,...

We present an approximate analytical solution of the Cahn-Hilliard equation describing the coalescence during a first order phase transition. We have identified all the intermediate profiles, stationary solutions of the noiseless Cahn-Hilliard equation. Using properties of the soliton lattices, periodic solutions of the Ginzburg-Landau equation, we have construct a family of ansatz describing c...

Hot deformation behavior of a medium Cr/Mn Al6061 aluminum alloy was studied by isothermal compression test at temperatures range of 320 to 480 °C and strain rates range of 0.001 to 0.1 s −1. The true stresstrue strain curves were analyzed to characterize the flow stress of Al6061. Plastic behavior, as a function of both temperature and strain rate for Al6061, was also modeled using a hyperboli...

We describe a method for converting the problem of computing steady-state probabilities of a continuous-time Markov chain into the problem of computing absorption probabilities for a related chain. The construction enables us to apply compositional techniques for computing absorption probabilities that we have previously developed for probabilistic I/O automata to be used for computing certain ...
